FLYING TOY.

To all 'wlw-m 'it may concern: Be it known that I, ALFREDL.' SALVO, citizen of the United States, residing at Augusta, in the county of Richmond and State of Georgia, have invented certaln new and useful Improvements in Flying Toys, of which the following is a specificatlon.

This invention relates to toys, having more particular reference'to a toy comprlsing| a helix adapted to be projected into the air by the imparting of rapid revolving motion to the appended claims in whichthe various novel features of the invention are. more particularly set forth.

Fig; 1 of the drawings is'a detail per spective view of my improved toy.

. Fig. 2 is a part side view and part axial sectional view thereof. A

Fig. 3 is a fragmentary axial section showing a modified form of toy.

Fig. 4 is a like view showing another modil fication.

Referring now particularly to Figs. 1 and 2 of the drawings my improved toy comprises a handle 10 of substantially cylindrical outline having fixed to and projecting from its upper end, co-axially therewith, a rod 11.

Freely surrounding this rod is a sleeve 12 which rests-upon the upper end ofthe handle, disengagement of the sleeve 12 from the rod 1l being prevented by a head 13 on the rod i .which is located n an enlargement at the to rotate with the sleeve.

The helix 15 may be conveniently made of sheet metal stamped to proper shape, the helix here shown being of the four bladed type, although any suitable number of blades may be employed.

Specification of Letters Patent. Patented June 20, 1922,

Application l'ed February 1, 1922. Serial No. 583,416.

Rotation is imparted to the sleeve 12 by means of a cord 18 which is wound around a grooved portion 19 of the sleeve and is rangementI in which the, sleeve 12 is provided with a diminished upward projection l2a on which the helix 15 rests, the latter. being formed with a number of radial slots 23 into which project resilient pins or fingers 24 carried by the sleeve and presenting outwardly bowed upper portions 24 which yieldingly hold'the helix 'on the sleeve. In this arrangement, when the sleeve is spun,

the helix is held in place until it Aattains suiiicient speed to develop a lifting force 'sufficient to overcome the resistance of the sprin pins 24.

In ig. 4 I have shown a further modification in which a. pair offresilient fingers 28 are fixed at one end in the sleeve 12" and project longitudinally outwardly through radial slots 29 therein and through radial slots 30 in the helix .151, having hooked free ends 28 which engage over the helix andhold it on the sleeve 12b when the rods are pressed inwardly by winding the cord 18 on the sleeve. ,V

When `the toy is spun these rods 28 remain in operative position until, the' cord is unwound, when they spring outward and release the helix.

' Having thus described my invention what I claim as new and desire to protect byA Letters Patent of the United States is as follows:

l. A toy comprising a handle, a rod projecting therefrom, a sleeve swiveled on said rod, a helix seating on said sleeve and having apertures through which said pins pro-` ject, and resilient fingers carried by said sleeve and yieldingly gripping said helix to hold the latter against axial movement with respect to said member during initial rotary movement of the helix, said helix being adapted to be automatically disen- TQS gaged from said'fingers pressure thereof ir cause nby'rdtationo'f the helix at high speed.

2. A `toy comprising a handle,a member rotatably mounted thereon, a helix seating lof in an axial direction against the latter caused by rotation of the helix at high speed.

3. A toy comprising a handle, a sleeve rotatable on said handle, a helix seating freely but non-rotatably on said sleeve, and resilient gripping elements yieldingly engaging said helix to hold the latter` against b an axial' direction aalnst the latter axial movement with respect to said sleeve during initial rotary movement of the sleeve, said helix being adapted to be automatically disengaged from said gripping elements by pressure thereof in an axial direction against the latter caused by rotation of the helix at high speed.

4. A toy comprising a handle,- a sleeve rotatable n said handle, and a helix seatin yfreely but non-rotatably on said sleeve, an

means other than gravity holding said helix on said sleeve during initial rotary move' mentof said sleeve, said'means comprisin resilient fingers projecting through radia slots in said helix and engaging the slot Walls. In testimony whereof I have aixed my signature.

ALFRED L. SALVO.,
